ABSTRACT

Huge amounts of data have posed great challenges to traditional data analysis methods for information and knowledge extraction. Data mining (application of lowlevel algorithms for revealing hidden information in a database) (Klosgen and Zytkow, 1996) has emerged as a new research field and a new technology in the last decade. Data mining represents the interdisciplinary research of several fields, including machine learning, neural network, statistics, database, visualization, and information theory (Koperski et al., 1996).
